We have evaluated bone scans, parathyroid hormone (PTH) levels and bone mineral densities (BMDs) of hemodialysis (HD) patients. The bone scans were grouped into 4 types (type 1-4). Type 1 showed a diffusely high activity of the tracer in the whole skeleton especially in the skull: secondary hyperparathyroidism pattern. Type 2 showed high background activity, the same pattern as osteomalacia. Type 3 was a mixture of types 1 and 2. Type 4 was almost normal. The PTH levels of type 1 were higher and the radius BMDs were lower than those of the other types. The radius BMDs in one third of type-2 patients were lower than the normal range. A comparison of bone scans, PTH and BMDs helps to evaluate bone changes in HD patients.
我们评估了血液透析（HD）患者的骨扫描、甲状旁腺激素（PTH）水平和骨矿物质密度（BMD）。骨扫描分为4种类型（1 - 4型）。1型显示示踪剂在整个骨骼中弥漫性高活性，尤其是在颅骨：继发性甲状旁腺功能亢进模式。2型显示高背景活性，与骨软化症相同模式。3型是1型和2型的混合。4型几乎正常。1型患者的PTH水平较高，桡骨BMD低于其他类型。三分之一的2型患者桡骨BMD低于正常范围。骨扫描、PTH和BMD的比较有助于评估HD患者的骨变化。
